What seems to be the issue?
42. The mean is the total of the numbers divided by the amount of numbers. In this case the amount of numbers is 7 and the mean is 6. That means that the total of the numbers divided by 7 equals 6. To find the total you just do the opposite, multiply 7 by 6 and you get 42.
Answer:
3(3+4)2= 42
